The digital world we work in keeps changing just like our work environments. As cybersecurity analysts, we try to understand and boost our defenses against many possible threats. Insider risk presents a special challenge that needs a different approach compared to external attacks.
Insider risk isn’t always about bad intentions. It can come from accidental actions, like when an employee falls for a phishing trick, sets up a system wrong, or loses a device. It also includes cases where outside actors steal an employee’s login information. With more people working in hybrid environments, our digital borders have grown. This means we need to control who can access what and when. We need strong measures to protect sensitive info and key infrastructure.
The Key Role of Privileged Access Management (PAM)
This is where Privileged Access Management (PAM) tools have a big impact on our security plan. In simple words, PAM aims to manage, watch, and secure all privileged accounts and what they do in a company. These privileged accounts have high-level permissions allowing them to access critical systems, applications, and data.
PAM reduces insider risk through several key principles:
• Enforcing the Principle of Least Privilege: PAM ensures users only have the minimum access required to perform their job responsibilities and only for as long as they need it. This limits the potential for damage if their account is ever compromised and decreases the overall risk of attack.
• Secure Credential Management and Vaulting: Instead of having employees directly access credentials for sensitive and important systems, PAM tools vault these credentials in a secure location. PAM tools allow organizations to manage access to certain credentials dynamically by making the access occur at the time access is acquired. Dynamic access to sensitive passwords reduces the opportunities for end users to directly or indirectly expose sensitive passwords.
• Session Monitoring and Recording: PAM tools allow administrators to access session monitoring and recording, which provides a detailed log of all actions taken when using elevated privileges. This information log is critical to holding users accountable for their actions, allows organizations to identify strange behavior, and enables organizations to conduct investigations of security events.
• Just-in-Time Access: Many PAM tools provide temporary access to a critical system. This limits the opportunity for abuse or misuse. When privileged access is active, it only lasts for the specific task that requires access.
• Mandating Multi-Factor Authentication (MFA): PAM tools often require strong MFA to authenticate privileged accounts and start privileged sessions. Using strong MFA allows organizations to add an additional layer of security beyond traditional passwords.
Increasing Our Posture of Security
Effective PAM use provides us with a number of important security advantages:
• Less Attack Surface: By restricting who is granted privileged access and when a possible adversary has fewer points of entry to take advantage of.
• Better Compliance and Audit Readiness: PAM assists us in fulfilling many legal and regulatory obligations related to data security, auditing, and access control.
• Increased Visibility and Control: Because of centralized administration and thorough overview of privileged activities, we have a better understanding of vital operations and can more easily identify and address anomalous activity.
• Simplified Incident Response: PAM’s comprehensive logs and session recordings enable us to look into possible security incidents and provide useful forensic information.
A Holistic Approach to Security
While PAM is an important part of our strategy, it is only one piece of a bigger security plan. Our approach to reducing insider risk also includes:
• Security Awareness Training: Regularly educating employees about common threats like phishing and social engineering and promoting secure computing practices.
• Data Loss Prevention (DLP) Solutions: Using tools to stop sensitive data from leaving our organization without permission.
• User Behavior Analytics (UBA): Implementing systems that analyze user activity to identify behavior changes that might signal a threat.
• Thorough Offboarding Procedures: Making sure all access privileges are removed promptly when an employee or contractor leaves the organization.
Effectively addressing insider risk is vital for maintaining the integrity and strength of our organization. By combining proactive security measures with Privileged Access Management as a key aspect, we can significantly improve our ability to protect our digital assets and maintain a strong security posture in today’s complicated threat landscape.
